ᐅ Air-to-water heat pump – smart thermostat

Against the stove, we have the air conditioning – it’s all a matter of proper planning.

Because you overestimate them or they are noticed through the return flow if they were that strong – which I still find hard to imagine in winter.

And a fireplace is a special feature that normally has no place in a modern house. I also ordered one because I don’t mind and I can still safely open a window.

But you haven’t understood how the individual heat carriers and especially the hydraulics of a underfloor heating system work, and what a thermostat can mess up.

By the way: I planned an exhaust hood – crazy, right?

I know of four houses with heat pumps in my personal circle that each got rid of the EER – and strangely enough, not only save noticeable electricity but also nobody suffers from overheating. That’s theory versus practice…

I think you’re just claiming that we don’t understand it, but you don’t bring a single real argument or explanation. That’s not how this works. You apparently overheard somewhere that EER is basically useless and you just pass that on – that’s how it looks to me.
By the way, overheating caused by the sun or a fireplace is not immediately noticeable either, often only much later due to thermal inertia. The return temperature reacts way too slowly to events like a fireplace or sun exposure.
Whether it works better or worse without EER in a house in your personal environment depends heavily on the circumstances. Using that as an argument is complete nonsense. Of course, you can’t heat efficiently with a heating curve turned all the way up and a constantly throttling EER, and then save after hydraulic balancing and without EER. But that’s not the fault of the system itself, it’s due to incorrect settings by the heating installer.
When you turn on the fireplace, you enjoy the warmth and simply save less energy than you could because the heating system overall delivers too much heat (you don’t notice it since it’s cozy warm anyway).
With the right design and heating system, the EER should basically only switch off in the situations I mentioned, like sun, fireplace, or comparable occasions (e.g., a family gathering with a few kilowatts of manual heating power), and otherwise stay open. In that case, removing the EER saves exactly 0°C (0°F); on the contrary, it becomes more expensive. But apparently, that’s not so easy to understand.
Especially when aiming for something like KfW40 standard, I consider an EER extremely important. For standards like the Energy Saving Ordinance 2009 or similar, of course, it matters less.

This topic has been discussed everywhere so many times... anyone who understands the technology knows that ERR doesn’t bring any benefit in a modern house...

and I can speak from experience... three years without it... not heating the heat transfer medium at all—that’s where the savings actually are, not by shutting down individual heating circuits...

@Bautraum 2015
Yes, a fireplace doesn’t bring anything except romantic atmosphere and sauna vibes, and of course, mess afterwards...

It seems you didn’t read or understand my post properly! Without EER in well-insulated houses, it’s easy to overheat the heat transfer medium unnecessarily! The EER provides a quicker higher return temperature and allows the heat generator to respond to the additional input energy. I would also ask you to provide real arguments instead of repeating the same thing over and over.

Sure, I can translate that for you:

Yeah, of course, I see many arguments from you and I’m happy to let you continue with them. They are indeed extremely important tools in a slow-moving system.

And overheating of the heat transfer medium? Please explain that to us in detail – so far, it’s just been hot air.

From you. As in this post. I did not write about overheating but was responding to Mycraft’s post. At least try to follow the discussion if you cannot contribute anything technical.

I told you – he just can’t do it.
